KNIFE-SHARPENER..

SPECIFICATION forming part of Letters Patent No.` 612,912, dated October25, 1898.

Application led July 28, 1898. Serial No. 687,091. No model.)

To all whom it may concern.-

Beit known that I, ROBERT E. POINDEX- TER, a citizen of the UnitedStates, residing at Indianapolis, in the county ofMarion and State ofIndiana, have invented certain new and useful Improvements inKnife-Sharpeners, of which the following is a specification.

My invention consists in an improved construction and arrangement ofparis in detail of a knife and scissors sharpener, whereby such a toolisprovided which will be inexpensive, convenient to use, and verydurable, as will be hereinafter more fully described and claimed.

Referring to the accompanying drawings, which are made a part hereof,and on which similar letters of reference indicate similar parts, Figurel is a perspective view of one of my improved knife-Sharpeners inposition for use, a knife being shown in the position it occupies whenbeing sharpened therein. Fig. 2 is a front elevation o f the same, the

,position of a knife and a scissors blade being indicated by dottedlines on opposite sides of the device in the positions they will occupywhile being sharpened; Fig. 3, an elevation of the rear side of thedevice; Fig. 4, a top view, and Fig. 5 a longitudinal central sec'- tionon the dotted lines n: in Figs. 3 and 4.

In said drawings the portion marked A represents the base-block, and Bthe sharpening-steel.

The base A consists of a cast-metal block provided with suitable meansfor attachment to a bench, table, or other convenient place, such asscrew-holes, as shown, and has an upright portion divided into threeparts by vertical slots, said parts being the side uprights A and thecentral upright A2. Each of said uprights is formed with its top abeveled to the degree required to support a scissorsblade when laid in aflat position thereon to present its edge to the cutting edge of thesteel, so as to give said edge the proper bevel after being operatedupon. The inner edges ce are also beveled, both vertically from the topdown toward the steel, which they nearly approach midway thereof, andtransversely from front to back toward the steel. This bevel d is suchas will furnish a rest for the side of the knife-blade when laid againstit in position to bring its opposite edge against the cutting corner ofthe steel to sharpen it as it is drawn through the space between thesteel and the said beveled portion a'. The base A is cut out justbeneath the steel B, so as to permitof the vertical adjustment thereofwhen desired, as will be presently described.

The steel B is simply a rectangular piece of chilled steel of propersize, and may be :made of scraps or small portions, such as would beordinarily thrown away around a saw-manufacturin g establishment.vertical slot, and is thus made vertically-adjustable on the screw.V b,by which it is secured to the central upright A2. By this means it canbe adjusted to bring substantially the entire length of its edges intouse, and when the edges of one side are worn to a point where they arenot eective the steel can be reversed and the other corners used, thusaording a very long life to the device and making it very inexpensivecompared with its usefulness.

In use the knife is placed against the bevel a', iirst on one side andthen on the other, with the edge in contact with the proper corner ofthe steel, and drawn its length until said corner has operated to cutsaid edge down to the desired degree. When it is desired to give theblade a bevel back from the edge, it can be held so that the corner ofthe steel will cut on the blade back of the edge until the bevel desiredhas been secured and then it may be held up to said corner to put on thecutting edge, as will be readily understood. To sharpen scissors, theblade is simply held fiat on the bevel a and the blade drawn backagainst the cutting corner of the steel until the edge is brought to thedesired degree of sharpness.

Having thus fully described my said invention, what I claim as new, anddesire to secure by Letters Patent, is

l. A sharpening-tool for blades, consisting of a base, the uprights Aand A2 with the ven tical slots between them, the central upright A2being formed with straight parallel sides, and the steel B mounted onsaid central up right and formed of greater width to entend It is formedwith a beyond the edges thereof and nearly across for the blades andsupport them in position to be drawn across the cutting Corner of saidsteel to be sharpened, substantially as set forth.

2. The combination of the base A, formed with uprights A and A2 withslots between them, each of said uprights A being formed With thebeveled portions a at the top and the beveled portions 0L ou theiradjacent sides 1o to support the scissors and knife blades respectivelyin position to be sharpened, said
